Résumé / Abstract

The analytical solution of the Ornstein-Zernike equation with a Sogami-Ise type closure for a multicomponent fluid discussed in our previous work (Yasutomi and Ginoza 2000 J. Phys.: Condens. Matter 12 L605) is extended to a more general case that c_ij(r) = Σ_n=1 Σ^L_τ=-1 K_ij^(n,τ)z_n^r+lr^τe^-znr σ_ij < r where C_ij(r) is the direct correlation function, r is the interparticle separation, K_ij^(n,τ) and Z_n are constants, σ_ij is the distance at contact of the pair (i, j) of particles. Almost all of the interaction potentials between particles (such as a potential due to diffuse electric double layer, van der Waals potential, steric potential and so on) can be well approximated by the above closure. In this sense the present analytical solution will be applicable to a large variety of colloidal fluids under the mean-spherical-approximation (MSA).
